1 Claim, 2 Drawing Figures DISPOSABLE SAFETY ROTARY RAZOR SUMMARY OF THEINVENTION This invention relates to a new and completely new concept ina safety razor. This new, one unit, inexpensive, disposable rotary razorprovides a super floating action shave. It has fewer parts than anyshaver on the market today. In addition, it also has less parts in thecomplete unit than can be found in just a blade dispenser itself. Thisrazor is easy to use and, because of its principles, gives a reallyclean, close and comfortable shave. Because of its unique design, thisinvention lends itself well to practical manufacturing.

This safety rotary razor is made inexpensively, is of one unit, and canbe thrown away after a plurality of shaves by the user. It can be madeof bright colored plastic. It employs a plurality of blades, forexample, six blades. The blades are adhesed to an hexagon-shaped plasticinner spool.

This one-unit spool holder and handle are made of an inexpensivebrightly colored plastic and can have a shim of semi-flexible teflonplastic material which is cylindrically shaped and adapted to be fittedwithin said outer spool holder and adhesed to the inner surface of saidouter holder in a manner to serve as a blade shield and blade wiperreed. This dual function is accomplished through the provision of anelongated slot extending lengthwise of said cylindrically shapedsemiflexible shim, the edges of said slot being turned inwardly alongthe length of said slot to form blade wiper reeds which are arranged topress inwardly and contact the blades to wipe said blades as they moveout of shaving position.

Two spool plug ends with a red markeron them can fall in line with thelast blade which also has a thin red line on it to remind the user thathe is on his last blade. This will give him ample time to buy andreplace the razor in use.

To change the blade, all one has to do is to hold the spool, plug endbetween his thumb and first finger (left hand) (cutting edge up), andmove the handle down until a clicking sound caused by the passing of thenew blade as it is rotated past the inwardly pressing blade wiper reedwhich is in close contact with said new blade as it is rotated intooperative position and a new blade comes into view. It is again readyfor use.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings: FIG. 1 is an explodedview of my invention; and FIG. 2 is a side view of my invention in use.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring now to FIG. 1, ahollow elongated plastic semi rigid sleeve 10, open at both ends, has anaxially extending slot 12. A plastic handle 30 is secured to the centerof the sleeve and extends at right angles thereto. An elongated hexagonshaped plastic spool 14 has an axial bore 16. A separate stainless steelblade 18 is secured to each of the axially extending faces with acutting edge which extends thereout. A thin flexible teflon sleeve 20with an axial slot 22 having inwardly turned blade wiper reed edges isdisposed axially within the sleeve 10 wi th slot 22 aligzned with slot12. Spool 14 is disposed within the sleeve 0 so that the cutting edge ofa blade extends outwardly and downwardly from the aligned slots 12 and22 for use in shaving. Control knobs 24 have axially extending pins 26which engage opposite ends of the spool. These knobs have alignedmarkers 28 which will point to the last blade in use after all otherblades have been successively indexed at the slots for use whereby theuser knows he should throw the entire unit out and obtain a replacement.

While I have described my invention with particular reference to thedrawings, such is not to be considered as limiting its actual scope.

I claim:

1. A disposable safety rotary rotary razor comprising:

A. an elongated semi-rigid outer cylindrical sleeve open at both endsand having an open slot extending axially throughout the length of saidsleeve,

B. a handle fixed to the midpoint of said sleeve and extending at rightangle thereto,

C. an elongated hexagonal spool disposed within said sleeve and manuallyrotatable therein on an axis parallel to the wall of said sleeve, saidspool having in cross section the shape of a hexagon with each of itssix flat faces extending the entire length of said spool,

D. six separate stainless steel shaving blades, each of said bladesbeing fixed to one of the flat faces of said elongated spool extendingthroughout the length thereof and each of said shaving blades having acutting edge protruding outwardly from said,

spool extending beyond the flat faces to which each blade is fixed,

E. each of said six blades being rotatable with said spool and means toindex each of said blades opposite the open slot of said elongatedsemiqigid outer cylindrical sleeve and the cutting edge of each bladeadapted to protrude outwardly through said slot,

hexagonal spool and a control knob for each end of said spool, eachcontrol knob having a pin adapted to enter said bore in a manner to fixsaid control knobs to opposite ends of said spool and manually rotatesaid spool,

G. a semi-flexible cylindrical shaped shim adapted to be fitted withinsaid semi-riged outer cylindrical sleeve and to surround said elongatedhexagonal spool which is disposed within said sleeve whereby both saidshim and said spool are disposed within said semi-rigid outer cylinder,said shim being adhesed to the inner wall of said outer cylinder andsaid spool being rotatable within both said shim and said outercylinder,

II. an open slot formed in said cylindrically shaped semi-flexible shimsaid slot extending parallel to the open slot of the semi-rigid outercylindrical sleeve in which it is disposed and to which it is adhesedsaid slot having inwardly turned edges along the length of the slot toform blade wiper reeds and arranged to press inwardly against andcontact the blades as they are rotated and moved out of shavingposition.
